Swedish architects at the firm of CF Moller have unveiled plans for a massive indoor ski resort which, when built, will be the largest in the world. Dubbed Skipark 360°, the new resort would ensure plenty of powder, even in the worst of winters, and could enable year-round fun on the slopes.

Thanks to its main slope, which is 2300 feet in length and has a drop of 515 feet, Skipark 360° will be the only indoor ski resort capable of hosting a World Cup event. That means skiers and snowboarders will have an impressive slope to shred 365 days of the year. The perpetual winter fun doesn’t end there however, as the resort will also feature more than two miles of cross country ski tunnels, a biathlon arena, ice hockey rink, and a separate rink for figure skating. Visitors will also find a hotel, spa, multiple restaurants and shops, and even a conference center. In short, everything they need in one self contained environment.

The architects have designed Skipark 360° to be environmentally friendly as well. The resort will get its electricity by a combination of solar, hydro, and wind power, and it will incorporate geothermal heat sources to keep the place warm. The goal is to use 100% renewable energy sources to limit the carbon footprint.

Construction on Skipark 360° is set to commence in 2013 in Balsta,which is located a short drive from Stockholm. It is estimated that the resort will cost about $290 million to complete.
